Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The present invention is a special fixation device conforming to the anatomy and biomechanics of the cervical and thoracic segments of the spine. The structure is as follows: Figure 1-7 As shown, including the titanium plate body, one end of the titanium plate body is the neck end 1, the other end of the titanium plate body is the chest end 2, the width of the chest end 2 is greater than the width of the neck end 1, and there are several connections between the chest end 2 and the neck end 1 Segment 3, thoracic end 2, cervical end 1, and connecting segment 3 are integrally structured, and thoracic end 2, connecting segment 3, and cervical end 1 form a smooth "S" shape, which conforms to the anatomical shape of the cervical and thoracic spine, so that the titanium plate body has Good adhesion, a pair of screw holes 6 are opened at the ...

Abstract

The invention discloses a special fixation device conforming to the anatomy and biomechanics of cervical and thoracic spine, comprising a titanium plate body, one end of the titanium plate body is the neck end, the other end of the titanium plate body is the chest end, and the width of the chest end is greater than the width of the neck end , there are several connecting sections between the thorax and the neck, the thorax, the neck and the connecting section are integrated and the thorax, the connecting section and the neck form a smooth S shape, which conforms to the anatomical shape of the cervical and thoracic spine, making titanium The board body has good adhesion. There are a pair of screw holes on the chest end and the neck end. There are threads in the screw holes and matching screws. There is also a locking nail hole between the pair of screw holes. A locking nail is cooperatingly arranged in the nail hole, and the locking nail hole and a pair of screw holes are located on a straight line. The nail cap of the locking nail can hold the screw cap, and the bone grafting window is formed between the locking nails. The invention solves the problem that there is still a lack of anatomical special fixing plates for this part at home and abroad.

Description

technical field [0001] The invention belongs to the technical field of spinal internal fixation devices, and in particular relates to a special fixation device conforming to the anatomy and biomechanics of cervical and thoracic segments of the spine. Background technique [0002] The Cervicothoracic Junction of the spine usually refers to the area where the cervical spine gradually transitions to the thoracic spine, generally referring to the cervical 6 to thoracic 2 segments. This segment is relatively special in anatomy, specifically, the physiological curvature of the cervical spine is lordosis, and the physiological curvature of the thoracic spine is kyphotic. Therefore, this segment is a region that gradually shifts from cervical lordosis to thoracic kyphosis . In terms of biomechanics, the cervical and thoracic spine is located between the cervical spine with the largest range of motion and the thoracic spine with the lowest range of motion, and is one of the parts of...
